The Pass Labs XP-12 preamplifier elevates your audio system. Engineered for professionals and discerning listeners alike. At its core is a newly designed toroidal power supply featuring both electrostatic and Mu-metal shielding, along with vacuum impregnation and epoxy fill. The result is minimal electrical and mechanical noise, supported by advanced multi-stage filtering for an exceptionally clean power rail.

Volume control is handled by a single-stage attenuator borrowed from our XS line, offering 100 precise 1 dB steps with reduced noise and distortion. Gain is delivered through high-bias Toshiba transistors and an auto-bias output stage—optimizing drive capability for long or multi-cable connections and simplifying the single-ended output path.

Compact yet robust, the XP-12 combines industry-leading performance with practical versatility—ideal for high-end studios, executive boardrooms, or sophisticated home theaters.
